B, dark mould proof processing: BAMBOO UNFOLDING plate places dark mould proof process container, steam pressure 0.2-0.8MPa, temperature Degree is 80-130 DEG C, time 3-6h；Fast-growing Eucalyptus peeler log veneer is placed on dark mould proof process container, and steam pressure is 0.1-0.6MPa, temperature are 60-110 DEG C, time 1.5-4h；
C, microwave treatment: Surface microwave explosion is carried out to BAMBOO UNFOLDING plate, power is 8~16KW；
D, it dries；It is dried using net belt type, temperature when BAMBOO UNFOLDING plate is dry is 65-85 DEG C, dry 60~75h；Speed Temperature when raw Eucalyptus peeler log veneer drying is 60-75 DEG C；Moisture content will be 6%-10% after the two is dry；
E, glue applies: using low-methoxyl aldehyde urea-formaldehyde resin adhesive, BAMBOO UNFOLDING plate resin added is aged 15- in 190-220g/m2 20min；Fast-growing Eucalyptus peeler log veneer glue application amount is aged 20-25min in 200-240g/m2；
F, splicing；According to the design specification and density of lamination square bar, plate is quantitatively weighed, plate is prolonged into longitudinal rift grain direction and is put It sets, staggeredly parallel stacking enters in feeder equipment layer by layer for BAMBOO UNFOLDING plate and fast-growing Eucalyptus peeler log veneer, and feeder equipment will be spread The raw material installed pushes in hot press, and splicing temperature is 80-130 DEG C, positive pressure 1.0-3.5MPa, and lateral pressure is 0.5-2.0MPa；Time is 5-25min；
G, it health: is stacked in square stock is smooth at gravity-flow ventilation, health 7-12 days；
H, cut out and divide: specification as needed is cut；
I, it examines point etc., repairing and packaging: cutting rear laminated timber and test, divide etc. and repairing, then again by grade packet It is packed into library.
As further technical solution of the present invention: the microwave blasting time in the step C is 3~6min.
Compared with prior art, the beneficial effects of the present invention are: the bamboo and wood laminated timber that the present invention makes, it is this to solve market The missing of plate, had not only played the good rigidity of bamboo wood, but also overcame large scale Eucalyptus easy to crack, torsional deformation and physical mechanics property Can be low the problems such as, solves the missing of this plate in market, enriches dalle and furniture woods, meet regeneration or circular economy and The requirement of green environmental protection；The added value of bamboo wood and Eucalyptus is improved, there is preferable economic interests and social benefit.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common Technical staff's every other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.
In the embodiment of the present invention, a kind of production method of bamboo and wood laminated timber comprising the steps of:
A, it stocks up: by BAMBOO UNFOLDING plate and fast-growing Eucalyptus peeler log veneer, growth 300-2400mm, width is respectively cut 100-400mm, thick 1.5-7mm；
B, dark mould proof processing: BAMBOO UNFOLDING plate places dark mould proof process container, steam pressure 0.2-0.8MPa, temperature Degree is 80-130 DEG C, time 3-6h；Fast-growing Eucalyptus peeler log veneer is placed on dark mould proof process container, and steam pressure is 0.1-0.6MPa, temperature are 60-110 DEG C, time 1.5-4h；
C, microwave treatment: Surface microwave explosion is carried out to BAMBOO UNFOLDING plate, power is 8~16KW；
